Acute appendicitis is one of the most common conditions requiring emergency surgery. However, acute appendicitis presenting with left lower quadrant abdominal pain is extremely rare. ⋯ The malpositioned inflamed appendix was clearly identified in the left side of the abdomen, with the characteristic CT findings of uncomplicated intestinal malrotation. Left-sided acute appendicitis should be considered in the differential diagnosis of young patients presenting with left lower quadrant pain, in order to avoid delay in diagnosis and guide the surgical intervention.
